Secured t the upper end ofthe spindle 5 a short distance above the collar 9 is a heady 13 from which, projects four arms 14:

substantially radially and at the ends thereof are attached the'rods" or bars 1-5 parallel to each other and spaced apartas shown. The rods or'bars'15 are adapted to support and carry garmenthangers'of any preferred type from'whichmay depend ready made garments position for ready inspection and display and readily removable there- 'from.. v

A pair of.bell crank levers 16 are pivot-V ally-mounted on the head 13, each comprising an upwardly extending arm and a'ihorizontal arm, said horizontal arms extending I outward from the headin opposite directions and each having a link 17 pivotally attached thereto, said links extending" downward and being secured at their 'lower ends to the collar, 9 by means of the ears 18integraltherewith as shown. J To each upwardly extending arm of the bell crank levers a link 19 is pivotally attached and the links extend outwardly in directions opposite to each other I and 'terminate Within the rods or bars Which are hollow and which are perforated to receive the flattened ends'20 of said links 19. With the collar 9 in normal position with projections12 seated'in notches 8, the

ends of links 19 reach to the sides of the 'ro'ds 15op positethe sides through whichentrance is had to the rods, and it is evident that the parts normally occupy such positions through the weight of collar9 tending toseat the projections in the-notches.

As a means of elevating the collar 9 and freeing the notches'8 of the projections 12 thereonthrough movement given to one of v the links 19, I have provided the following structure. Projecting, in either direct on from the end 20 of the-links 19 withinthe rods 15 are a pair of sheet metalmeinbers 21, and near one end of each ofsuch mombers' there is provided a handle member 22 located onthe outside of the rod'15 and pro -jecting horizontally therefrom, said handle being secured to the member 2l'by the pin 23 extending; through slot 2 1 in'the'rod 15. A; short distance from the end 20 of 19,"v said sheet=-metal member is given a quarter. tur nja'nda portion: is cut away asat 25"and the' -extrl'enie end fashioned with an; inclined: i point 26, which passes a very little way under the end 'of part'20 on one side thereof.v The'companion member 21 onxthe other side "is similarly formed and its pointed-end is seated in similar manner'with relation to the other side of the portion-20 The shoulder at 27-for1ned by cutting away. the member 21:. serves as a seat for the spring 28 which at handles.-

its other end rests against a projection 29 secured tothe sideof therod 15 and project-' j ing therein. Spring 28 is normally under compression and works to forcejmembers 21 away from the end 20 of link 19,"and" forcing the handle 22 to its extreme of movement defined by the boundary of slot 24,- as shown in Fig; 4. There are four ofthese members 21 oneonea'ch 's'ideof thelink ends-:20 and all are similarly constructed andmounted in the rods 15 so that whichever rod ispre sented 'at the front of the rack,-there is presented to the operator two handle members which he'may grasp to operate the locking device for unlocking and freeing the rack for on-the-rod's 15 is a matter ofj choiceand they maybe located at any desired distance from 7 rotation. Y The positioning of the handles 22 i the middle point of the rods, there being I shown in Fig. 'l

varying locations of the r VlZ-ith the rackgwithin a case or compart-T ment, itis desirable th'at the rods 15 be parallel to the backof the case and the relation of the collars 7 and 9 and notches and pro- 990 jections Sand 12 is such that with the projections seated in'the notches and the rack lockedfrom rotationfthe' rods are held parallelto the back of the case." W hen drawn forward-therein and access to the articles held by the rear rod is desired, the rack must be unlocked and rotated. i The unlocking is accompllshed by grasping either handle 22 presented on the front "bar andpressing it toward the middle of the bar. Such opera-tion causes the member 21" to move: lengthwise of the bar, compressing spring 28 and forcing" inclined end 26' ofsaid member 21 underthe end of :link 19 thereby operating it toward the: centerof the head: 13', turning; the2bell crank leverf at-] tached thereto about itspivot and elevating the horizontal arm thereof and elevating link I 17 i and the collar 9' attached thereto and thereby carrying-projection 12 above the i notch '8 and disengaging therefrom. The, elevation of the collar 9.corres'pondingly elee vates the other link 17 and draws the other link. 19 inward ,but'there 'isnothingto interfere and prevent such movement, it tak-g ing place without causing any appreciable sense as limiting the invention to any parany (as of the mem ers 21 by its longitudi The above described construction while practically operative and complete is not to be considered other than a diagrammatic representation :of the invention, and in no ticular specific construetion. The invention is defined in theclaims, andall modifications in structure properly falling Within the scope thereof, are to. be considered as comprehended inmy invention. 5

WVhat I claim as new and desire by Letters Patent is a 1. In combination, a support, a rack member mounted thereon for rotation, said rack member including parallel rods, means for locking the rack member infixed relation to the support, a plurality of separate means mounted on the rack member and independently associated with the locking means for manual operation thereof to free the rack for rotation, each of said manually operated means including a device mounted within said rods and mounted to move lengthwise thereof and engaging elements of the locking means and operating the same to unlock the rack and free it for rotation on such lengthwise movement.

2. In combination, a support, a rack member mounted thereon for rotation, said member including parallel rods, means for looking the rack member in fixed relation to the support, means for manually operating said locking means to unlock and free the rack for rotation, said locking means having elements connected thereto and extending to the rods, and said manually operated means including elements mounted on and movable longitudinally of the rods and engaging to secure with the said connected elements, said elements of the operating means being formed to move the said connected elements on longitudinal movement of the operating elements in one direction and thereby operate the locking means to free the rack for rotation.

3. In combination, a support, a rack member mounted thereon for rotation, saidrack member including parallel rods, and a centrally located head, means to lock the rack member in fixed relation to its support, de-

vices mounted on the head, connections between said devices and thelocking means,
